Description:
------------
when some elements in array are changed by reference and this array is then converted using
mb_convert_encoding, these elements are removed or empty. Warning is emmited
"mb_convert_encoding(): Object is not supported in ...", but function returns result
without mentioned elements. Best see in code example.
Test script:
---------------
// any sample array, structure does not matter
$array = [
'ads' => [
123 => ['name' => 'this', 'id' => 444],
234 => ['name' => 'that', 'id' => 555],
],
'other' => ['one', 'two']
];
// we modify array elements using reference
foreach( $array['ads'] as &$ad ){
$ad['premium'] = (int)($ad['id'] == 555);
}
// print_r prints array contents OK
print_r($array);
// mb_convert_encoding emits Warning, but returns result where modified array elements are removed -
in this case 'ads' element
print_r(mb_convert_encoding($array, 'UTF-8', 'UTF-8'));
Expected result:
----------------
array elements does not disappear, mb_convert_encoding does not emit warning
Actual result:
--------------
mb_convert_encoding returns result where modified array elements are removed. mb_convert_encoding
emits warning
